3W SINGLE & DUAL
OutputOverCurrentProtection
To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry
and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from
voltage control to current control. The unit operates normally once the output current is brought back into its
specified range.
ShortCircuitryProtection
Continuous and auto-recovery mode.
During short circuit, converter still shut down, The average current during this condition will be very low and the
device will be safe in this condition.
RemoteON/OFFControl
The positive logic remote ON/OFF control circuit is included.
Turns the module ON during logic High on the ON/Off pin and turns OFF during logic Low. The ON/OFF input
signal (Von/off) that referenced to GND. If not using the remote on/off feature, please open circuit between on/off
pin and -Vin pin to turn the module on.
The negative logic remote ON/OFF control circuit is included.
Turns the module ON during logic Low on the On/Off pin and turns OFF during logic High. The On/Off pin is an
open collector/drain logic input signal (Von/off) that referenced to GND. If not using the remote on/off feature.
Please short circuit between on/off pin and –Vin pin to turn the module on.
